Specification of Letters Patent.

Paten ted July Al 5, i913.

Serial No. 604.009.

To all fin/wm t may concer/i f Be it known that l, ltuoonrii (lounlnmn,a citizen of the United States. residing at Erie, in the county offlllrie and State of Pennsylvania7 have invented new and usefulimprovements in Pumps. of which the following is a specification.

This invention relates to pumps and consists in certain improvements invthe constii'uction thereof as will be hereinafter fully described and.pointed out in the claims.

More particularly, the invention relates to` that type of pumps used inArtesian wells, especially oil wells, and is directed more par ticularlyto devices for connecting the sucker rod with the standing valve so thatthe standing valve may loe lifted for renewal, repair' or for drainingthe pump.

The invention is illustrated in the accent panying drawings as follows:

Figure l shows a cross section on the line l-l in Fig. 2. Fig. 2 shows acentral vertical section through the plunger and standing valve. Fig. 3a transverse section en the line 3MB in Fig. 2. Fig. 4 a central sectionthrough the plunger. Fig. 5 a perspective view of the trunnion andconnected parts at the top of the well. Fig. 6 a central section throughthe standing valve and working barrel showing the standing valve in anelevated position. Fig. 7 a central section through the working barreland adjacent parts and showing the actuating means at the top of thewell.

l marks the strainer common to pumps of this class, 2 an extension onthe working barrel7 and 3 the working barrel proper or that part. of theworking barrel having the working surfaces. The extension 2 has thestanding valve socket lin which is placed the standing valve 5, thevalve having the usual packing G which is to effect a joint. Thestanding valve crown 7 forms the usual. cage for the standing valvecheck S.

The plunger 9 as shown is tubular and simply provided with metalsurfaces which operate in conjunction with the surface of the workingbarrel. It has the crown l0 in which is arranged the spider 1l formingthe connecting means for the sucker rod connection l2. A plunger valve13 is secured to the sucker rod connection and operates on the valveseat let at the bottom of the crown l0. rlhe sucker rod connection hasthe shoulder 15 which limits the downward 'movement terminating in thescrew ttl on which the sticker rod 1T is screwed. ln the operation ofthe pump with this type of plunger' valve, the ojgieration of theplunger valve does not depend on the fluid. pressure, but on thedownward stroke of the sucker rod, the valve is forced downward awayfrom this seat, the frictional engagement of the plunger with theworking harrel resisting this movement. The collar l5 permits thedownward movement of the sucker rod connection 12. On the retllrn strokeof the pump7 the sucker rod connection slides upwardly through thespider 'll until the plunger valve seats. This seating of the; valve notonly closes the valve but also forms the lifting connection with theplunger so that with a further movement ofthe sticker rod, the plungeris lifted. l

lt is desirable to lift the standing valvel for the purpose of renewalor repair and also for the purpose of draining the pump. l provide ascrew connection between the sucker rod connection and the standingvalve by means of which the standing valve may he connected with thesucker rod connection so as to he lifted. I prefer to form thisconnection with a yielding screw so that as the parts are broughttogether, the screw, threads are not injured and lvet the engagement ofthe screw practically assured. A. rod 18 is screwed into the top of thestand ing valve crown l and locked in position hy the jam nut 19. Ahitting 20 is screwed on to the top of the rod, this fitting beingtelescopically arranged within the plunger 9. The fitting has the sideguide pieces 2l connected by the perforated transverse portion Q2 inwhich is arranged ascrew 2 3. rlhis screw is adapted to engage the screwZ-t in the valve l?) as the sucker rod connection is lowered intoengagement with the screw 23. The screw 2&3 has the head 25 which slidesbetween the guides 2l and is locked by the guides against rotation. Aspring E2G is arranged within the guides and is tensioned against thehead of the screw 2.5. The rod 1S has a small projection 27 whichextends within the spring to lock it in position and the head 25 has thepro- 105 jection 2S which extends within the spring for the samepurpose.

llVhen it is desired to couple the sucker rod connection with thestanding valve, the plunger is lowered. and the sucker rod is turned soas to rotate the sucker rod connection 12. As this connection and valve13 are lowered, the screw 23 yields so as to prevent any jamming orinjury of the threads. At the same time, the spring forces the screwupwardly so that the entry of the thread is assured. The yieldingmovement of the screw 23 is sufficient to allow the lower end of thevalve 13 to contact the top of the fitting 20 so that regardless of howthe plunger and sucker rod connection may be lowered, the screw cannotbe injured.

In order to bring the screw 24 into engagement with the screw 23 it isnecessary to lower the plunger to a position on the nut 19 as shown inFig. 4. As the parts are screwed together, the valve 13 will be securedbelow the seat 14 and as the parts are lifted the plunger is preventedfrom dropping down to close the valve 13 by reason of the fact that itis resting on the nut 19.

The tube 31 is connected by the coupling 39. to the working barrel 3 inthe usual manner and extends to the top of the well. 'Ihe sucker rod 17terminates with the usual polished rod 32. This polished rod is attachedto the polished rod adjuster. The rod extends into the body 34 andthrough the eye bolt 35, the eye bolt being arranged in the body. rIheeye bolt has the projection 3G and the nut 37 is arranged on thisprojection. By means of the nut 37 pressure may be exerted on the eyebolt so as to clamp the rod in place. The polished rod 32 extendsthrough the eye bolt and as the eye bolt is forced sidewise is clampedin position. This has the ordinary construction for adjusting thepolished rod. A screw thread socket 38 is arranged in the top of theadjuster and the pipe 39 is screwed into this socket. A portion at leastof the pipe 39 is screw threaded and is screwed through the head 40ofthe trunnions 41. The triinnions are arranged in the usual bearings onthe walking beam 4Q.

IVhen itis desired to lift the standing valve, the walking beam isstopped at its lowest position and the pipe 39 on sucker rod adjusterlis screwed down thus lowering the plunger to a position where the screwthreads 24 of the. valve 13 will engage the screw 23. As the sucker rodsare turned down, it will be noted that the sucker rod connection 1'2turns in the plunger so as to relieve the plunger of the turning action.The pipe 39 is preferably provided with a nut 43 for indicating theposition where the sucker rod connection is brought into engagement andalso with the nut 44 for indieating the clamping position and forlocking the pipe in adjustment in the triinnion head.

It is often desirable to simply lift the standing valve and dischargethe liquid from the tube so as to clean the valve surfaces or flood thewell. By making the extension Q larger than the standing valve and ofsuflicient length to form a bypass around the standing valve when thestanding valve is lifted, this can be readily accomplished withoutlifting the plunger from the working barrel. In'Fig. 7 the plunger islowered and the sucker rod connection has been screwed into engagementwith the screw 23. In Fig. 6 thestanding valve as shown is lifted intothe extension 2. It will be readily seen that the liquid can pass aroundthe standing valve and be discharged. It will also be noted that whenthese parts are in engagement, the valve 13 is opened so that the liquidfrom the tube can pass through the plunger.

I prefer to arrange a flange nut 30 in the bottom of the plunger formingan internal shoulder which will engage the bottom of the fitting 20 andthus lift the standing valve. This scheme of lifting the standing valvecan be utilized should the screw connection become disarranged, or whereit is not important to drain the tubing.

I do not claim broadly in this application a yielding connection betweenthe plunger and standing valve or a yielding bolt on the plunger orstanding valve as these features form the subject matter of applications#604,007 and #604,008 filed on even date herewith.
